IGNITION DEVICE FOR, GAS-STOVES.

To all whom it may concern:

Be it known'that I, FRANK V. KNAUss, a citizen of the United States, and residing at Portsmouth, in the county of Scioto and State of Ohio, have invented a new and useful Improvement in Ignition Devices for (irasStoves, of which the following specification is a full disclosure.

My invention relates to ignition means for burners of gas stoves or ranges, and primarily in providing gas conveying channel, receiving and conveying an ignition supply of gas from that escaping from the burner, after opening the burner controlling valve to an accessible and convenient point of safety beyond the burner flame zone.

An object of the invention is to provide a gas burner with a gas conveying channel or conduit as a temporary pilot for igniting the burner at a point of safety from the burner, with the gas utilized for ignition purposes conveyed from the gas escaping from the burner, after opening its controlling valve, and the mouth of the channel constructed in proximity to an end of the burner so as not to form an obstruction to the burner after ignition.

Another object is to provide a means for entraining a portion of the gas from a burner to the exterior of a gas stove at a point remote from the zone of combustion,

said means being positioned to utilize the draft created by the burner when lighted to prevent an entrainment of flame or unburned as therethrough.

The eatures of the invention are more fully set forth in the description of the accompanying drawings, forming a part of' this specification, in which Figure 1 is'a front elevation of a gas stove, partly in section, to show the oven burner. Fig. 2 is an enlarged section on line 2,2, Fig. 1. Fi 3 isa top plan view with two of the stove ids removed to show the burner construction. Fig. 4 is an enlarged section on line 4.-4:, Fig. 3. Fig. 5 is an enlarged section on line 55, Fig. 4c.

This invention in a gas range provides a burner lighting device for lighting the top burners without removing the stove lids, or the oven burner without opening the oven door. By a direct lighting of the gas burners there is the always present danger of injury to the operator, while with my improved device, the point of lighting is re- Specification of Letters Patent.

mote from the zone of combustion or at a point of safety.

The stove comprises the usual box-like body portion 1, supported on legs 2, and provided with a top plate 3, having a stack 4 and flame apertures closed by lids 6. Gas burners 7 are positioned in the burner chamber 5, concentric with the flame apertures and connected to the supply conduits 8, each provided with mixer attachments 9 and regulating valves 10, leading from the manifold pipe 11.

Each burner 7 is provided with a lighting channel plate 12, which in cross section is preferably of inverted \l-shape, (see Figs. 4 and 5), its upper end terminating with a flange portion 13 bolted to the under surface of the top plate 3. By providing elongated bolt slots 13 in said flange the plate 12 is rendered adjustable to regulate the amount of gas entrained thereby. The channel '14 of this plate terminates with an aperture 15, which is in registry with a lighting aperture 16 in the top plate, the wall 17 of the aperture 15 being extended downwardly to form an abutment or guide for directing the gas upwardly through the lighting aperture 16.

The plate 12 is inclined downwardly, its

lower end extending over jet openings 18, 18, of one of the burner arms. The angle of inclination of the plate 12 is of a degree which will cause the gas escaping from the jet openings to travel upwardly within the channel 14 and through the alined apertures 15 and 16 at which point the gas is ignited by a match or other means, the burner igniting flame descending to ignite the burner. The month end of the channel formed by the plate 12 is arranged so that it will not interfere, after ignition, with the combustion of the products escaping from the burner aperture covered by the plate 12, and the channel is such as will not convey deleterious vapors to the lighting aperture 16, as there is practically'no draft therealong to influence over the flue draft of the stove. This construction provides a means for entraining a portion of the gas from the burner to a lighting aperture remote from the zone of combustion, and in a closed top stove the burners may be lighted without removing the lids 6. In Figs. land 2, T have illustrated th pilot channel plate applied to a different style of burner, namely to one of the oven in an inclined upwardly direction, to an exit or igniting aperture 24, within the oven walls, and adjacently alined with an aperture 23 through the Wall 25. The aperture 23 provides an entrance through the wall to the igniting aperture 24 of the pilot channel plate 22, through which a lighted match or taper may be inserted to ignite the gas escaping through the aperture 24.

From the foregoing it will be apparent that channel plates provide a temporary pilot for igniting'the burners, taking its ignition supply from the escaping gas of the burner after opening its valve, and carry the ignition point to a point of safety beyond the burner, making the pilot control positive and dependent upon the control of the burner.

While ,I have illustrated the inclosed burner type of stove, following the modern requirement especial for natural gas burners, it is obvious that my burner ignition means is equally applicable to open burner stoves or different types of burners, with the concept of the invention, and do not Wish to be limited to the structural design disclosed, except wherein specifically so limited in the claim.

I claim A device of the nature disclosed comprising a gas burner, a burner chamber having an apertured wall, the aperture being located remote from the zone of combustion of the burner, and an inclined plate secured to the chamber wall adjacent the aperture, having a channeled under surface terminating at the aperture through the wall, said plate having an aperture therethrough registering with said wall aperture, the opposite end of said inclined plate straddling over a portion of the burner gas jet openings.

In witness whereof, I hereunto subscribe my name, as attested by the two subscribing Witnesses.
